Hey
Missing maps at the moment: Rialto, Havana, Blizzard World and Numbani
Will they be returning or are they terminated because they are incompatible with OW2 physics and gameplay. Anyone knows or have some theories? 
Don’t forget Junkertown which was removed due to an apparent bug, and is allegedly coming back on the 25th with the Halloween event.
As for the others, your guess is as good as anyone’s.
They’ll be back next season. Map pools are back
